Hijama (Cupping) while Fasting … – (Hanbali Fiqh)

Answered according to Hanbali Fiqh by TheHanbaliMadhhab.com

Hijama (cupping) breaks the fast according to the Madhhab. This ruling is restricted to cupping, and thus any other type of removal of blood, like donating blood, does not invalidate the fast.

This applies both to the one doing the Hijamah and the one getting it done.
